Answer:
From DRAM to DDR4
Explanation:
RAM stands for <em>Random Access Memory.</em> In 1968, Mr. Robert Dennard at IBM's Watson Research obtained the patent for the one-transistor cell that will eventually substitute the old magnetic core memory allocated in computers of the time. By 1969 Intel released the TTL bipolar 64-bit SRAM (Static Random-Access Memory) as well as the ROM "Read Only Memory"; also in 1969 it evolved into "<em>Phase - change memory - PRAM - </em>". However this evolution was not commercialized, Samsung expressed its interest in developing it. In 1970 the first DRAM product was commercially available; it was developed by Intel. In 1971 it was patented EPROM; in 1978 George Perlegos developed EEPROM.
By 1983 a nice breakthrough happened with the invention of SIMM by Wang Labs. In 1993 Samsung came up with KM48SL2000 synchronous DRAM (SDRAM), this variation soon turned into an inductry standard.
In 1996 DDR began a revolution in the memory sector, then in 1999 RDRAM. Both DDR2 SDRAM. DDRR3 and XDR DRAM were commercialized. Finally in 2007 and 2014 the developments of DDR3 and DDR4 were available for the general public.

Answer:
Open systems
Explanation:
Open systems are very different from Open Source applications or software, it should not be confused.
Open systems work with the blend of open software standards, portability, and interoperability. Computer systems that interoperate among multiple standards and vendors to ensure that computer resources (hardware and software) are not allotted to a particular vendor. Such computer systems are considered as open systems.
For instance, computer systems that run a Microsoft Windows OS can be considered as an Open system. This is because of their capability to run different versions of the Microsoft Windows OS on that particular computer system. More clearly, A computer with Windows 10 OS, can be used to install Windows 8 OS without any issue. That same computer system can run the Windows 7 OS. This makes the computer system and open system.
Answer:
As a design rule, access points within range of each other should be set to channel frequencies with minimal signal overlap. Users will find that roaming doesn’t work well, and performance will degrade because of interference between access points.
